Several remote vulnerabilities have been discovered in strongswan, an implementation of the IPSEC and IKE protocols. The Common Vulnerabilities and Exposures project identifies the following problems: The charon daemon can crash when processing certain crafted IKEv2 packets. (The old stable distribution (etch) was not affected by these two problems because it lacks IKEv2 support.) The pluto daemon could crash when processing a crafted X.509 certificate.
